Lots of great 3D printed upgrades available here as well: https://www.fine-scalemodela.com/ah-64-apache1.html
For power system, 1700 rpm should be a good target. That’s around a 1400 KV motor with a 14T pinion. Do not use less than a 13T pinion as it puts a lot of stress on the gear. The old RC Aerodyne manual actually had a warning against this printed in it.
If you have any questions on the build, feel free to send me a PM or post here. I think over the past few years, I’ve managed to find just about every random issue that it could throw at me.
